Spanning an extraordinary 35 meters in length and 16 meters in width, this expansive acrylic panel transforms the swimming pool at Tentrem Hotel, Semarang into a striking architectural centerpiece. Designed to create a seamless visual connection between the pool and its surrounding space, the monumental acrylic installation offers an immersive perspective into the water from multiple angles. Beneath the surface, swimmers are surrounded by an intricate mermaid mosaic embedded into the pool floor, adding an artistic narrative to the underwater experience. More than a structural element, the installation transforms the swimming pool into an architectural experience—where transparency, water, art, and modern design converge on an exceptional scale.
